Handlebar-Mounted Cyclocomputer Knob for Stable Page Turning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cyclocomputers require page-turning operations that disrupt cycling balance and safety due to the need for finger movements perpendicular to the handlebar, necessitating a safer and more ergonomic input mechanism.
Innovation Solution
A cyclocomputer with an adjustment knob mounted on a holder that allows page-turning via a finger while holding the handlebar, featuring ergonomic dimensions and non-slip surfaces for safe and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If page-turning keys are disposed at different positions on the cyclocomputer body, then the user can access different data pages, but the user's hand position must be moved which disrupts cycling balance and safety
Solution Approach 1:
The patent combines multiple data page access functions into a single adjustment knob located at a fixed position on the cyclocomputer body. This allows users to access different data pages by rotating the same knob in different directions or positions, eliminating the need to move hand position between separate keys and thereby maintaining cycling balance and safety.
2Ease of operation
If keys are used for page-turning operations, then data pages can be turned, but the finger must apply force in a direction different from the holding direction which disrupts cycling balance
Solution Approach 1:
The patent inverts the traditional key-pressing operation by using a rotation-based adjustment knob. Instead of pressing keys perpendicular to the handlebar holding direction, users rotate the knob along the handlebar axis, allowing the finger to apply force in the same direction as the holding direction, thereby maintaining cycling balance.
3Ease of operation
If the adjustment knob is positioned too far from the handlebar, then it is easier to operate the knob, but the user's finger cannot reach it while holding the handlebar
Solution Approach 1:
The patent optimizes the distance parameter between the adjustment knob and the handlebar to a specific range that balances operability and reachability. This parameter optimization ensures the knob is positioned far enough to be easily operated but close enough to be accessible to the user's finger while maintaining the handlebar grip.
4Length of moving object
If the adjustment knob is positioned too close to the handlebar, then the user can easily reach it, but it becomes difficult to operate the knob without moving the hand position
Solution Approach 1:
The patent optimizes the distance parameter between the adjustment knob and the handlebar to a specific range that balances operability and reachability. This parameter optimization ensures the knob is positioned far enough to be easily operated but close enough to be accessible to the user's finger while maintaining the handlebar grip.
